You can use a TableModel.
您可以使用一个TableModel.
Define a class like this:
定义一个这样的类：
public class MyModel extends AbstractTableModel{
//not necessary
}
actually isCellEditable()is falseby default so you may omit it. (see: http://docs.oracle.com/javase/6/docs/api/javax/swing/table/AbstractTableModel.html)
实际上isCellEditable()是false默认的，所以你可以省略它。（参见：http: //docs.oracle.com/javase/6/docs/api/javax/swing/table/AbstractTableModel.html）
Then use the setModel()method of your JTable.
然后使用setModel()你的方法JTable。
JTable myTable = new JTable();
myTable.setModel(new MyModel());

You can override the method isCellEditable and implement as you want for example:
您可以覆盖方法 isCellEditable 并根据需要实施，例如：
//instance table model
DefaultTableModel tableModel = new DefaultTableModel() {
@Override
public boolean isCellEditable(int row, int column) {
//all cells false
return false;
}
};
table.setModel(tableModel);
or
或者
//instance table model
DefaultTableModel tableModel = new DefaultTableModel() {
@Override
public boolean isCellEditable(int row, int column) {
//Only the third column
return column == 3;
}
};
table.setModel(tableModel);
Note for if your JTable disappears
注意您的 JTable 是否消失
If your JTableis disappearing when you use this it is most likely because you need to use the DefaultTableModel(Object[][] data, Object[] columnNames)constructor instead.
如果您JTable在使用它时消失了，那很可能是因为您需要改用DefaultTableModel(Object[][] data, Object[] columnNames)构造函数。
//instance table model
DefaultTableModel tableModel = new DefaultTableModel(data, columnNames) {
@Override
public boolean isCellEditable(int row, int column) {
//all cells false
return false;
}
};
table.setModel(tableModel);

just add
只需添加
table.setEnabled(false);

这对我来说可以。

If you are creating the TableModel automatically from a set of values (with "new JTable(Vector, Vector)"), perhaps it is easier to remove editors from columns:
如果您从一组值（使用“new JTable(Vector, Vector)”）自动创建 TableModel，也许更容易从列中删除编辑器：
JTable table = new JTable(my_rows, my_header);
for (int c = 0; c < table.getColumnCount(); c++)
{
Class<?> col_class = table.getColumnClass(c);
table.setDefaultEditor(col_class, null); // remove editor
}
Without editors, data will be not editable.
没有编辑器，数据将不可编辑。

create new DefaultCellEditor class :
创建新的 DefaultCellEditor 类：
public static class Editor_name extends DefaultCellEditor {
public Editor_name(JCheckBox checkBox) {
super(checkBox);
}
@Override
public boolean isCellEditable(EventObject anEvent) {
return false;
}
}
and use setCellEditor :
并使用 setCellEditor ：
JTable table = new JTable();
table.getColumn("columnName").setCellEditor(new Editor_name(new JCheckBox()));
回答by Oleg Mikhailov
table.setDefaultEditor(Object.class, null);

I used this and it worked :it is very simple and works fine.
我使用了它并且它有效：它非常简单并且工作正常。
JTable myTable = new JTable();
myTable.setEnabled(false);
